Antibiotics have long been important in helping us to maintain our health, yet low doses of antibiotics have been given to animals for years to help them gain weight. Can you say Catch 22? Remember the obesity issue?
Scientists are now saying that antibiotics make small changes to the billions of microbes living in the digestive tracts of animals.
And your human body comes with microorganisms that break down food and take its nutrients, but antibiotics kill some of the organisms. That allows microbes in our intestines to absorb more calories.
